To all whom it may concern:

Be it known that I, FRANK Drn'rnron WARD, residing at New York city, New York, and being a citizen of the United States, have invented certain new and useful improvements in lVheel-Making lilachines, of which the following is a ull, clear, and exact description, such aswill enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawin s, which illustrate the preferred form 0? the invention, though it is to be unthe exact details of construction shown and described, as it is obvious that various modification's thereof Within the'scope of the ap pended claims will occur to persons skilled in the art.

In said drawings: Figure 1 is a view partly in side elevation and partly in longitudinal, vertical section of an embodiment of the present invent-ion. Fig. 2 is a view partly in top plan and artly in longitudinal, horizontal section t ereof. Fig. 3 is a transverse, vertical section taken on the looking inthe direction of the arrow. Fig. i is a rear end elevation thereof, the drive shaft being seen in section. Fig. is a transverse vertical section taken on the plane indicated by line 55 of Fig. l and. looking in the direction indicated by the arrow. Fig. 6 is a front end elevation. Fig. 7 is a transverse vertical section takenon the planes indicated by line 7-7 of Fig. 1 and looking in the direction of the arrow. Fig. 8 is a fragmentary, detail, top plan view of the rear portion of the structure, parts being broken away.

The object of this invention is the production of a mill or machine intended to be used in the manufacture of car wheels, though it is obvious that other shapes and articles may be manufactured in a machine constructed in accordance with the invention, and it is intended that the metal blank or billet to be worked in the machine shall he first subjected to oressnre after which it is preferably rolled in such manner that a portion of the metal near the middle of the blank shall be forced outwardly radially during the lcondensation formation of the blank into the finished product.

- Refe ring to the drawings by numerals,

Fixed to and rising from bed plate 1, at each side and intermediate the length thereoi, are pedestals ll, each terminating at its upper end in a sleeve l for receiving: and sup portin the respective guiding and connecting rot or bar 5, one of the rods 5 being arranged at each side and connecting the rout frame 2 to the rear frame 3, each of said frames being tormed with elongated sleeves 6 for receiving the given ends of the re spective rods Each rod 5 is threaded at each end and engaged at the opposite ends of the respective sleeve 6 by jam nuts 8, rigidly retaining the bar in position.

Fixed to bed plate 1 transversely thereof and intermediate its length, is an inverted. channel or other suitably shaped stop nierm her 9, having its front edge formed relatively smooth and vertical, and having its rear edge formed into a reel: 16. A guide late 11 is mounted upon and tired to inemher 10 and to the bed plate in any suitable manner by through bolts, the plate ll having forwardly extending guiding arms 12-l2 extending along the bed plat-e near the opposite edges thereof and lined thereto. Each arm 12 has its upper directed inwardly and spaced above the bed plate for accommodating and guiding a slide hloch' 13, which is slidingly mounted on the bed plate and has its edges overhung by the upper flanges of the respective arms 12. The rear end of slide 13 is adapted at times to pass beneath plate 11. and to be limited in its rearward movement by member 9. Mounted upon and fixed to slide18 is a die sustaining carriage i l, having a central, horizontal, longitudinal bore ll} accoxmno dating the die carrier shaft 16, the rear end of which shaft terminates in an annular plate or die carrier 13' which disposed at the rear end of carriage ll. Said rear end of carriage 1a is formed with a flattened annular surface surrounding the rear shaft 16 and abut-ting flat against the front exposed surfaces of die carrier 1?, Car

end or riage 14 is formed with journal bearings 16 and 16 receiving the journal portions of shaft 16, and the forward end of the shaft.

is formed with an annular groove receiving a split collar 16 for retaining the shaft against longitudinal shifting. Lateral arms 18-18 pro ect from carriage 14 and terminate at their outer ends in guiding sleeves 19-19 surrounding the bars 5, and limited in their rear-ward travel by nuts 2020 threaded on to the respective rods 5 and re tained against accidental displacement by jam nuts 21 also threaded on to the bars 5. For effecting travel of carriage 14 and the parts connected thereto, the arms 18 are engaged by pistons 2222, extending from cylinders 23-23, each provided witha fluid supply pipe 24, and adapted to receive fluid under pressure through said supply pipe for imparting the requisite rearward thrust to the pistons 22. Each piston 22 is guided by extension or sleeve 23 projecting from the v rear end of the respective cylinder 23. The

rear end of each piston 22 extends into a socket 18 opening forwardly from the re spective arm 18.

For effecting the forward or return travel of the carriage and parts carried thereby, the slide 13 is engaged by a pair of rods 25, which rods extend forwardly and engage the opposite ends of a cross block 26 fixed to a piston 27, which piston is mounted in cylinder 28. A fluid supply pipe 29 is provided for the cylinder 28 and adapted to deliver fluid under suilicient pressure for returning the carriage 14. The cylinder 28 is mounted upon and fixed to stands 303O fixed to bed plate 1, and each of the cylinders 23 is fixed to and carried by frame 2.

Mountedupon carriage 14 is a longitudinall disposed sleeve 31 through which exten s a drive shaft 32, the sleeve being formed with a journal bearing 33 at each end in which the shaft is journaled. front end of shaft 32 is formed with a squared portion 32 extending into and being slidingly engaged by a socket 32", projecting rearwardly from a stub shaft 32, journaled in bearing sleeve 32, and driven from-any suitable source of power, preferabl through a gear 32 fixed to the front end of the stub shaft. To the rear end of shaft 32 is detachably fixed a pinioni34 meshing with an annular gear forming a part of an annulus 35, surrounding and detachably fixed to die carrier 17. Detachably engaging the annulus 35 is a die 36. which is shaped, of course, in accordance with the finished product desired.

Fixed toand formed integral with the rear frame 3 is a transversely disposed guide plate 37, having a vertical face exposed forwardly, and its upper edge engaged by a plate 38 having a depending flange along its front edge to serve as a re- The r i'ainer for a slide plate 39, which slidingly engages plate 37 I and has an upstanding flange lapping the depending flange of plate 38. The plate 37 is preferably formed with a forwardly offset portion intermediate its width, and the slide plate 39 is correspondingly offset for providing a guide and support for the slide.

A transversely disposed cylinder 40 is fixed to frame 3 at one end thereof and extends toward the opposite end of the frame, and a piston 41 extends from the cylinder 40 and has its free end extending into a socket in slide plate 39. communicates with the cylinder 40 for supplying fluid under pressure for actuating the piston and shifting the slide and with it the rear end of die carrier 49 hereinafter de-.
